Answer:

Step-by-step explanation:

First, you can plot this using a table. One side can be 'Women' and the other 'Men'. One the vertical side of it, write '1980', '1981', '1982', etc., for maybe fifteen years to be on the safe side. Then, your starting value is 6 million and 5.4 million, respectively.

Finally, start adding up, It will be, 6.14 million, 6.28 million, etc., and 5.4 million, 5.48 million, etc.

Once you're done, you can circle the year both were the same, and you can even plot this on a graph

What are the factors of x2 – 100?
Komok [63]

Answer:

(x+10)(x-10)

Step-by-step explanation:

Given : x^{2} -100

To Find : What are the factors of  x^{2} -100

Solution:

x^{2} -100

Since 100 =10^{2}

x^{2} -10^{2}

using property : a^{2} -b^{2} =(a+b)(a-b)

(x+10)(x-10)

Thus  the factors of x^{2} -100 are (x+10) and (x-10)

Answer:

Total  probability value is 1

P(green) = 0.2 , P(brown) = 0.54

Given P(red) = P(yellow) = x

Total Probability = P(green) + P(Brown) + x + x

1 = 0.2 + 0.54 + 2x

1 - 0.74 = 2x

x = 0.13

P(red) = P(yellow) = 0.13

Now number of times it landed on each color :

On \ red :\\P(red) = \frac{number \ of \ times \ on  \ red}{1200} \\\\0.13 *1200 = number \ of \ times \ on \ red\\number \ of \ times \ on \ red\\ = 156\\

Since P(red) = P(yellow) , the number of time on yellow and red are same.

On \ yellow :\\number \ of \ times \ on \ yellow = 156

On \ green :\\P(green ) = \frac{number \ of \ times \ on \ green}{1200}\\\\0.2 *1200 = number \ of \ times \ on \ green\\\\number \ of \ times \ on \ green = 240

On \ Brown : \\P(brown) = \frac{number \ of \ times \ on \ brown}{1200}\\\\0.54 *1200 = number \ of \ times \ on \ brown\\number \ of \ times \ on \ brown = 648

Answer :

Red      156

Green   240

Brown   648

Yellow   156

Ivenika [448]

Answer:

<h2><em><u>7</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>B</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>129</u></em><em><u>°</u></em></h2><h2><em><u>8</u></em><em><u>.</u></em><em><u> </u></em><em><u><</u></em><em><u>N</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>85</u></em><em><u>°</u></em></h2>

Step-by-step explanation:

7. <A + <B = 180° <em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>

=> 51° + <B = 180°

=> <B = 180° - 51°

=><em><u> <B = 129° (Ans)</u></em>

8. <M + <N = 180° <em> </em><em>[</em><em>Since</em><em> </em><em>Co-interior</em><em> </em><em>angles</em><em>]</em>

=> 95° + <N = 180°

=> <N = 180° - 95°

=> <em><u><N = 85° (Ans)</u></em>
